Member Function Documentation

error()

void vcsn::detail::dot::driver::error	(	const location_t &	l,
		const std::string &	m
	)

Report an error m at l.

Definition at line 84 of file driver.cc.

Referenced by vcsn::detail::dot::parser::error().

Here is the call graph for this function:

has_edit_()

bool vcsn::detail::dot::driver::has_edit_ ( const location_t &  l )

private

Require that vcsn_context was defined.

But do it only once, no need to spam the user.

invalid()

void vcsn::detail::dot::driver::invalid	(	const location_t &	l,
		const std::string &	s
	)

The string s is invalid at l.

Definition at line 95 of file driver.cc.

parse()

auto vcsn::detail::dot::driver::parse	(	std::istream &	is,
		const location_t &	l = location_t{}
	)

Parse this stream.

Exceptions

Here is the call graph for this function:

setup_()

void vcsn::detail::dot::driver::setup_ ( const location_t &  l, const std::string &  ctx  )
